Hello!
I use matlab R2015b for Win Server 2012 OS with local parpool. I have memory leaks on local workers when function inside parfor-loop generate warning. Also memory is not released after parfor-loop ends. Example:
x = rand(78, 1);
for j = 1:100
parfor i = 1:1000
[~, z] = kpsstest(x);
end
end
[~, z] = kpsstest(x) generates warning:
Warning: Test statistic #1 below tabulated critical values:
maximum p-value = 0.100 reported.
> In kpsstest>getStat (line 632)
In kpsstest (line 291)
Memory leaks on workers even when i use constructions:
warning('off', 'econ:kpsstest:StatTooSmall');
pctRunOnAll warning('off', 'econ:kpsstest:StatTooSmall')
Memory on start workers:
Memory on after executing code:

This problem is the subject of this bug report. If you are able to upgrade to R2017a, that's the simplest workaround.
